That shouldn’t happen, as most firmware updates wouldn’t affect the wattage draw of the device. That said, it certainly can happen, and with devices beyond EVs as well that receive firmware updates that affect wattage draws. That should be a very rare occurrence though.
Once we get this fixed, I can share a bit more info, but essentially pre-firmware update, there was an odd spike in the signature (seemingly deviant). Our models were trained to look for that spike as part of the device. They’ve since smoothed out the ramp up, and it’s thus throwing our previously trained models off. This is the first time we’ve run into an issue like this and we’ve been working with some EVs for almost two years. I really don’t think this should be taken as a sign of things to come.
@samwooly1 let’s please keep this thread focused on EVs. You can take this separate convo to PMs.
